Note: The Sheriff's Office built in this step requires 5 Particulars. In order to get these without spending gold, you must build 3 other buildings (detailed below) and harvest each one several times to build the next. Two of the buildings, the Trading Post and Canyon Shop, are part of the Round Town quest. If you build them now, you won't need to build them later. You can pay 15 Gold for 5 particulars and build the Sheriff's Office that way. Alternately, you can skip this phase of the quest for 2 Gold. This leaves you without a Sheriff's Office, which may be used in future quests, requiring you to skip other phases.
